Specification of Letters Patent.

Application ined June 25, 1919. serial No. 306,755.

. T0 all 'LU/wm t 'may conce/rn.'

Be it known that I, KARL Eonmr'r, a citizen of the hepublic of Switzerland, residing at Fallanden, Switzerland, have invented certain new and useful Improvements in Beltlflolders for Looms; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will ena-ble others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates to belt fasteners for the belt or strap of the picker stick of looms.' i

It is well known that such belts are subject to variations in length, due to atmospheric conditions, and that a full shuttle requires a stronger impulse than one that is nearly empty. Long shuttles also require a greater impulse than shorter ones. 'By reason of this the belt or strap of the picker stick must be adjusted to suit conditions and these adjustments are often made within small measurements of a millimeter or so.

My invention has for its object a device on the picker stick for attaching the belt or strap to any adjusted length, so that the belt or strap can be easily and rapidly unfastened and fastened, for adjustment to prevailing conditions In the drawings, in which like parts are similarly designatedj Figure 1 is an elevation, partly in section.

Fig. 2 is a plan view thereof, and

Fig. 3 is an elevation of a mod iication.

The device comprises a Wedge-shaped casing 1 of rather heavy sheet metal, whose interior is also wedge shaped. The interior surface of the bottom of the casing is roughened, as indicated at 7. The sides of the casing at right angles to the bottom are bent over at the top toward each other with their edges spaced apart, thus forming a slot. A

bolt and nut 2 secures the holder to they picker stick 2%.A j

Coperating with the casing l, is a Wedge 6 having smooth faces and also having a portion 5 projecting above its upper face forming a handle that is free to pass between the bent over edges of the casing 1, as

clearly seen in Fig. 2.

By striking the nose or smaller end of the wedge 6 or the projecting handle 5 at said `end Awith a hammer the Wedge is easily loosadjustment of the strap or belt 4 the wedge 6 is re-inserted in the casing 1 and struck on its opposite larger end to force it into the casing and to force the under surface of the belt into engagement with the roughened surface 7. f

In the modification illustrated in Fig. 3 the wedge-shaped casing 1 is formed as a complete loop, and the wedge 6 in this instance, necessarily has the handle 5 omitted. The casing 1 is immovably connected to the picker stick 3 by the bolt, as illustrated in the drawing.

I claim:

1. A belt or strap fastener for looms, comprising a wedge-shaped casing having sides whose upper ends are bent over toward each other, and a wedge for insertion in said casing and having a portion projecting through the slot formed between said bent over edges.

` 2. In a belt or strap holder for looms, the combination with the picker stick; of a wedge-shaped casing whose bottom is interiorly roughened for engagement with a belt, means for securing said easing toa picker stick, said'casing having sides Whose upper edges are bent over toward each other, and a wedge ooperating with the wedgeshaped casing and having a handle projecting through the slot formed between the bent over edges.

3. In a belt or strap fastener for looms the combination with the picker stick; of a wedge-shaped casing interiorly roughened onr its bottom, a bolt passing through said bottom and securing the casing to the picker stick, the sides of said casing having their upper edges bent over toward each other to form a slot between them, a wedge having smooth surfaces, and a longitudinal central projection from its upper face forminga handle, said handle projecting through the slot formed between said turned over edges.

In testimony that I claim the foregoing as my invention I have signed my name.

KARL ECKERT.
